Beelink 8.0 Unstable. Downgrade 8 to 7 as final measure?

[jvanderaa]

I recently upgraded my proxmox cluster that is a bunch of NUC and NUC class (2 NUC, 1 Beelink) devices. They had been rock solid on 7.x and after using Debian 12 now for a few months as my primary Dev Workstation, I said let's move forward. However, the Beelink device is incredibly unstable. It may be something in it's NIC or otherwise as I see some errors in the syslog referencing interface down events. I have swapped cabling and interfaces to no solution, the node keeps losing connectivity and then getting fenced.

Is there some other t-shooting that can go into it? My thoughts of next steps would be:

1) I see there is a kernel update out today, going to try to get that in first
2) Attempt to reformat the node to 8.0.2 from a boot ISO
3) Attempt to downgrade the cluster to 7.x

How I would look to accomplish the downgrade, I don't know if this is possible or not. I would look to take one node out at a time and reformat with a 7.4 ISO image, going node to node and then rejoining to the cluster after the 7.4 image is on the host. Would the cluster support such a move?

In case it is using (a) Realtek NIC(s), have a look here:

That looks like the issue in fact that I'm facing. Appreciate the NIC reference that I missed on.

What I have done for now is to back down the the 5.x kernel and the system is running. When I tried to install the 8168 drivers the device went offline all together and lost the NIC. I tried to find updated 8169 drivers and failed to do so in my brief searching. So the 5.x kernel was the quickest way for now.

I also found beelink machine unstable after upgrade to 8.x recently.
Tried to remove amd64-microcode and move out lxc containers. Currently trying downgrade to 6.1 kernel. I was using 6.1 with PvE7.4 without such issue.
